November is sometimes called “the month of the Pleiades,” because this cluster is now so well placed for viewing in the evening sky.

Fred Espenak - Mr. Eclipse - posted this image at EarthSky Facebook last weekend. He wrote: "M45, the Pleiades star cluster. It's visible on November nights in the eastern sky as a tiny dipper-shaped clump of stars. Definitely one of the most beautiful open star clusters in the sky. This image is a stack of 20 individual 5-minute exposures through a Takahashi Epsilon 180ED Hyperbolic Astrograph using a Canon 6D DSLR." http://www.mreclipse.com

Last week, the space technology startup Lunar Outpost publicly displayed its rover concept – the Lunar Resource Prospector – for the 1st time. The rovers may help pave the way for a human return to the moon.

Late last month, a team of researchers said Earth’s oceans had warmed 60% more than anyone had realized. Now that result appears unlikely, since a mathematician and climate contrarian has uncovered a scientific error.
